I see your point, but we know all the elements that exist on Earth.. they're could be endless possibilities behond our planet. If we were to fall in contact with them, they would have to be at least slightly more advanced than us.

Ahem, before I begin please forgive me for any spelling or grammar errors. We look at our world as it is, but going to another world, studing its materials would be like entering another universe. In Earth we look at Hydogen as a normal thing, but alien life might look at it like a jewl, as they may have some unknown element that was part of everyday life in they're society, we would also look at it like a jewl. Now, this would trigger some sort of way to get that jewl, theres two options in this case. Our first idea would be to start some sort of trade route, but a trade route to us might look like a friendly jesture, but to them it could seem like a threat, causing a intergalactic war. The other choice would to be take it by force, which would still seem like a threat. again, causing mass genicide. How do we solve this problem? well most likely this option would never come to us, as we are measly humans are they are super intellegent beings, if they got some sort of commucation of us, they would most likely brush it off, as they have most likely found other life, and we are no surprise that there is life. As humans we are extonished by finding any evidence of life, our excitement getting out of hand, starting an accidental war. So, what I have learned from this is to just expect alien life to a point that we aren't surprised, just saying hello, then moving on. Once again, please forgive me for any spelling errors, criticism is accepted, thank you and have a wonderful day.

Disregarding all religous fronts. If you were to find a way to become eternal you would most likely not want it. As your skin would decay, your brain would basically turn into a rotten tomato, and after all existence ends you would be floating around in an endless void for the rest of enternity. Though, if there were a god, or gods, this will totally disapoint them, as you have cheated life. Though if you were granted some kind of power through religion you would most likely bend the whole society of the earth and you'd either call a heratic, or be worshipped as a god, also this would totally change the way the world looks at religion, they would most likely worship it radically wanting the power you have been granted, causing chaos across the world. Now, I hope I helped you understand Eternalism, please forgive me for any spelling errors as I am quite young and still learning. Have an amazing day!
